MIT hits the nail yet again by discovering a molecule that could beused best to store solar power. Called the Fulvalene Diruthenium – tinyparticle consists of two aromatic carbon rings, and transition metalwhich can act as a molecular heat battery instead of currently usedmolten salt which isn’t very efficient. The compound according to theresearchers stores heat in the form of a fuel. It can get as hot as 200degrees C and yet remain stable over long period. The reversiblecompound could be used anywhere, it could be heated and placed back inthe sun to recharge as well.
